The older twin brother of Dummac Tweedle and a member of Na'Ka'Ve's chapter of Oglaigh na Tír, Devonn (better known by his nickname Dee) was largely identical to his brother in appearance, with the major differences being that he liked to wear green and usually had a beard. He died setting off an Alchemist's Fire bomb while protecting Rilira Fl'wr. This had a dramatic effect on her, and obviously on his brother also.
